摘　　要：本文对狭窄矩形槽道内水平矩形翅片管束的自然对流放热进行了实验研究，揭示了矩形翅片和张力绕片椭圆管束的放热强度与板间距ｄ、管间距Ｓ１、Ｓ２及空气流通截面比ε等之间的关系，并整理出有关曲线和经验公式；对散热器的设计和改进有一定的实用价值。By experimentally researching the natural heat convection transfer of the horizontal rectangular aliform metal flake in narrow rectangular groove, this article reveals the relations among the radiative intensity of the rectangular aliform metal flake and elliptical pipes of tensile winded flake, and the distance between grooves(d), the distance between pipes(S 1,S 2), and the rate of air flowing sectional area(ε), and gives the relative curve and experimental formula. there should be practical value to design and improve radiator.
